Notes:

*1: Mechanism selection signal and the printing enable signal for 3” mechanism.

*2: Not used at the combination with 2” mechanism.

*3: At the mechanism side, this pin number is for the printing data 2.

Since this pin number is used for the printing data 1 at the interface board, the No. 15 and No. 17 pins are connected.

*4: This signal is used for the adjustment of printing duty depending upon the rank of thermal head resistor. Not used at this interface board.

•Symbol “——” means a negative logic signal.

•“I” or “O” means a signal direction from the interface board side.
